Working Principles

The TLC7701IPWR is a voltage supervisor IC that monitors the voltage level of a power supply. It compares the supply voltage with a programmable threshold voltage and generates a reset signal when the voltage falls below the threshold. The reset output is an active low/open-drain type, which can be connected to other circuitry for system reset or fault detection purposes. The delay time between the voltage dropping below the threshold and the generation of the reset signal is programmable, allowing customization based on specific application requirements.

Detailed Application Field Plans

• Automotive: Battery monitoring, ECU (Engine Control Unit) systems
• Industrial: Power supply monitoring, PLC (Programmable Logic Controller) systems
• Consumer Electronics: Home appliances, portable devices
• Medical: Patient monitoring equipment, medical instruments

Detailed and Complete Alternative Models

• TL7700IPWR: Similar functionality, lower operating temperature range (-40°C to +85°C)
• TL7702AIPWR: Higher number of threshold voltage options, wider supply voltage range (1.2V to 18V)
